Bit of a weird one but I've noticed in recent months that when I cum, after the initial 'burst', the semen almost just stays in the urethra. I have to 'squeeze' my penis like it's an aluminium tube to get the rest out. It isn't painful, or even particularly unpleasant but it's clearly not 'normal', compared to what should happen for me.
I'm 37, and have read that these sorts of things start to happen as you get older. It's nothing to worry about but is it normal at this age?
Also, I'm under investigation for a lot of other health issues. I'm almost certain I'll be receiving a diagnosis of chronic fatigue, with a side order of functional nerve disorder. I'm beginning to wonder whether the ejaculation losing its 'power' is caused by one - or both - of these things.
